本論文主要是提出並且證實全光學式光纖感測系統的可行性。在理論上，此光纖感測器是結合了多模光纖( Multimode Fiber ) 之光斑 ( Speckle ) 對於物理量改變的靈敏性與亂相編碼 ( Random Phase Encoding ) 之體積全像( Volume Hologram ) 多工儲存的技術。在實驗上，我們主要討論光纖受橫向位移量的影響下，系統與光纖光斑、光纖纏繞數目及毛玻璃之間的關係。實驗結果發現若增加光斑資訊可提昇系統的訊雜比 ( SNR )，若增加光纖纏繞數目的可提高系統的靈敏度，若加入毛玻璃有助於提昇系統的訊雜比。最後，我們利用實驗所得的結果將系統最佳化並且真正的實現了 “ 全光學式光纖感測系統 ”。
